TRACTION-HARVESTER.

Specification of Letters Patent.

Application filed August 6, 1913.

Patented May 12, 1914. Serial No. 788,272.

To all whom it may concern Be it known that I, CHARLES F. RADATZ, acitizen of the-United States, and a resident of the city of KenoshaHeights, county of Kenosha, and State of Wisconsin, have inventedcertain new and useful Improvements in Traction-Harvesters, of which thefollowing is a specification.

My invention relates to motor tractor harvesting machines and theobjectof this improvement is to provide a motor driven vehicle providedwit-l1 a harvester attachment which is adapted to be operated by themotor of said vehicle.

A further object is toprovide a simple and effective machine of thecharacter described.

Other objerts will appear hereinafter.

\Vith these objects in view the invention consists in the combinationsand arrangements of parts hereinafter described and claimed.

The, invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Figure 1 is a side elevation of a motor tractor equipped with anattachment embodying my invention, Fig. 2 is a perspective view of thesame, Fig. 3 is a bottom plan view of the same, Fig. 4 is an enlargedlongitudinal section taken on'line 44 of Fig. 3, Fig. 5 is an enlargedsection taken on line 55 in Fig. 4, F ig..(3 is an enlarged sectiontaken on line 66 in Fig. 4, Fig. 7 is an enlarged section taken on line77 in Fig. 1, Fig. 8 is a similar view taken on line 8-8 in Fig. 1, Fig.9 is an enlarged section taken on line 09 in Fig. 8, and Fig. 10 is anenlarged section taken on line 10-10 in Fig. l.

The preferred form of construction as illustrated in the accompanyingdrawings comprises a motor tractor provided with a harvester attachmentadapted for mowing. The motor tractor comprises a frame 11 mounted onforward ground wheels 12 and rear traction wheels 13. The tractionwheels 13 are mounted on an axle 14 provided with a bevel gear 15. Thebevel gear 15 meshes with a bevel gear 16 which is carried on a shaft 17journaled in the frame 11.

Hollowbearings l8 and 19 are carried by frame 11. Journaled in bearing19 is the rearward extending end of the motor driven shaft 20. The motordriven shaft 20 is provided with a restricted end 21.. Mounted on theend 21 is a hollow shaft 22 and provided with a clutch 23, of ordinaryconstruction preferably of the toothed clutch type, the shaft 22 beingslidably mounted on the end 21 to effect engagement and disengagement ofclutch members 23. The rear end of the shaft 22 is mounted on a shaft 24and the shaft 2-1 connected by means of a universal joint 25 with theshaft 17. A slot and pin connection 26 is provided between the hollowshaft 22 and the shaft 24 to cause simultaneous rotation thereof.

The bifurcated end 27 of lever 27' engages a groove 28 in the hollowshaft 22 'and said lever is pivoted at 29 to the frame 11. A spring 30normally maintains the lever 27 and hollow shaft 22 in a position toeffect disengagement of clutch members 23. A foot pedal 31 is providedin frame 11 and mounted on a rod 32 carried in said frame. The footpedal 31 is connected by means of a connecting link 33 with the lever 27to effect engagement of clutch members 23 as will be readily understood.A catch 34 is formed on the floor of frame 11 adapted to engage the rearend of pedal 31 to lock the pedal arm 35 in a position to maintain theclutch members 23 in engagement by. means of their connectin mechanism.From this construction it wil be seen that an operator may by engagingor disengaging clutch 23 by means of foot edal 31 cause the motortractor to be moved liy its own power.

On the outside of bearings 18 and 19 are mounted clips each composed ofmembers 36 and 37 each member 37 being hinged to member 36 as at 38. Ascrew 39 is threaded in member 36 and passed through member 37 toreleasably lock the members 36 and 37 in annular form around thebearings 18 and r 19. A casting 40 is carried by the members 36 andextends outwardly under the frame 11 substantially as indicated. On theouter end of the casting 40 is pivoted a shoe 41 carrying a conventionalcutter bar 42. Reciprocally mounted in the cutter bar 42 is aconventional sickle 43. The cutter bar construction being of any wellknown or preferred type. The sickle 43 is connected by means of a pitmanrod 44 to a crank shaft 45 journaled in the casting 40. The shaft 45also carries a spur gear 46 meshing with a larger spur gear 47. The spurgear 47 is carried by a sleeve 48 rotatively mounted on V by thebifurcated ends 49 of a lever 50. The

20 with a pedal adapte lever 50 is pivoted on the pin 29 of frame 11 andprovided with a spring 51 resiliently maintaining the lever 50 andsleeve 48 at its rearward terminal of movement. The other end of sleeve48 is provided with clutch members 52 engaging the corresponding clutchmembers onthe motor driven shaft '20.' The spring 51 normally maintainsthe clutch members 52 out of engagement, as will be readily understood.

The lever 50is connected by means of a connecting rod 53- to a pedal arm5& carried on' shaft'32. The pedal arm extends through the floor offrame 11 and provides a means for manually operating the clutch members52! The pedal arm is provided to engage a stop 55 to normally maintainthe clutch teeth 52 in engagement. This construction provides -.a meansfor manually engaging and disengaging clutch members 52 therebyefl'ecting operation and inoperation of the harvester attachment. Theharvester attachment is thrown into and out of operative conditionindependently of the mechanism throwing the tractor in and out of selfpropelling condition.

Pivot'a'll'y mounted on the shoe 41 is a lever 5'6'one end of which isprovided with a hook adapted to engage the pivotal connection betweenthe sickle43 and pitman rod 44 to limit the movement of the sickle 43from the cutter bar 42 when the latter is in vertical condition. Theother end of lever 56 is connected by means of a chain 57 to a handoperable lever 58'by means of which the cutter bar 42 is swung on itspivotal point from horizontal to vertical condition. An eye 59 iscarried by the casting 40 and connected by means of chain 60 to a handoperable lever 61 by means of which the cutter bar is raisedhorizontally from the ound. The operation of hand levers 58 and 61 onthe cutter bar are similar to their ordinary functions in conventionalharvestin machines.

Vhile I have illustrated and described the' preferred form ofconstruction for carrying my invention into efl'ect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, .but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.
